The numbers game

But you started at 1. You should have started at 0 now that we acknowledge that it exists - or perhaps doesn't but is too useful for our numbering systems.

When you get to infinity then you can use the infinity symbol. ;)

If I ever get bored of it I'll make it my last post :cool:

I didn't mean any one thing in particular; just asking :)

Have you been in John Lewis, rioted? :hmm::D

So engineers etc. can accurately pinpoint the location when reporting faults?
IIRC, There are permanent distance markers (which used to be in miles, furlongs and chains . . . probably not any more), gradients are marked on special posts, signals all have a number and area code, bridges are numbered in sequence and by distance too.

The spray painted '30' was, I'm guessing, a temporary marking of 30m, while laying track or cable.
